ABC has decided not to move forward with new seasons of “Castle,” which will now conclude after eight seasons, and perennially ratings-challenged “Nashville,” which would have been heading into season five. The cancellation of “Castle,” which had previously announced co-stars Stana Katic and Tamala Jones would not be returning, is a surprise given that Nathan Fillion recently renewed his contract.
Also not returning on ABC is the revival of “The Muppets,” musical farce “Galavant” and “Marvel’s Agent Carter,” the spin-off from “Marvel’s Agents of SHIELD.” The network did, however, issue a second season pick-up to sitcom “Dr. Ken.”
